Apple finally dusted off the MacBook Air. The 2018 model sports a brand new design, a gorgeous Retina display, and powerful upgraded internals. All of sudden, Apple’s most affordable notebook is up there with its best.

In fact, the new ultraportable is so good, you would be crazy to buy a 12-inch MacBook right now. So, how does the new MacBook Air stack up against the rest of Apple’s laptop lineup? Which model best suits your needs, and which delivers the best bang for the buck?

Apple may have seriously undersold the processing power of the iPhone XS.

After deep diving into the new A12 chip, which is the world’s first 7nm manufactured processor, Anandtech found that the CPU features some big improvements that make it perform way better than just the 15% boost Apple is advertising. It’s nearly as good as a desktop CPU.

The company and industry analysts point to weak demand for high-end smartphones as the main reason for the poor guidance. This likely has something to do with the fact that iPhone X sales have been in the gutter since early hype quickly died out late last year.

Intel plans to offload virus scanning to improve the performance of its processors.

It will allow antivirus programs to use its integrated graphics chipsets when scanning for attacks, which will reduce processor and power consumption on some machines. It could mean that you’ll get more use out of your MacBook in between charges.

Intel has confirmed that fixes for the widespread Spectre bug can cause unwanted reboots on many PCs. And if that wasn’t bad enough, the company has also revealed that its latest chips — including the Kaby Lake line launched in 2017 — are also susceptible to the bug.
